Dill Sheppard

Dill Sheppard is the effeminate son of Senator Sheppard that wants to live his own adventures. In "Haylias", Stan has similar problems with Hayley wanting to go off on her own and plots to have her and Dill get married by temporarily controlling her mind through brainwashing implanted during Project Daycare. At the wedding, things go wrong when Project Daycare was found to be defective, resulting in those brainwashed to turn into their controller's killers, forcing Stan to fight Hayley for his life. Hayley shoots and temporarily kills Stan, breaking the control. Hayley and Dill have the wedding annulled and they go their separate lives.

Dill also appears in the audience in "Phantom of the Telethon".

He makes a cameo appearance in "100 A.D." when the mob chops down the sign at the Chimdale Mountain Inn.

In "Stanny Tendergrass", he is a member of the Havercamp Country Club who is hustled by Roger and Stan when they set up a golf tournament.
